each : function(array, fn, scope){ //如果array中的元素为空,返回,不往下执行 if(Ext.isEmpty(array, true)){ return; } //如果array不是可迭代对象或者是JavasScript基本类型 string、number、boolean等,就将array放入一个数组中。 if(!Ext.isIterable(array) || Ext.isPrimitive(array)){ array = [...

In this lesson we will understand the For Of loop in Javascript which was introduced in ES6. The for-of loop lets you iterate of an itterable object (array, string, set, or map) and returns each objects value in a specified variable. This excludes plain objects as we will see in the...

Perform Checks on Every Element to Break Execution if Certain Conditions Are Not Met in JavaScript Some of you may have already noticed that when working with.forEach(), the associated function is always executed for every element in the array. That is not always desirable, especially if the ...
